what if 2x 320gb is still too much? I already have a wd black 1tb for my data, would like a raid 0 for my os and apps, anything from 100gb and up will be enough. Dont think they still sells hdd smaller than 320gb don't they?

The WD Caviar blue is the new name for the WD SE16 drives. See the model name here: WD 3200AAKS



And if you go with smaller HDD, you risk speed of the larger platter drives. The 320 and 640 GB versions of WD drives have 320GB platters, which are faster than smaller platters!

It doesn't cost much more for a 320GB drive compared to a 250GB, and more storage never hurts... they are quite a bit faster than the 250GB platter drives.

Read this post I made to explain it a bit...

The larger (more dense) the hard drive platters, the better the performance. The 640GB Caviar black has 2x320GB platters, therefore is faster than the 750GB version with 3x250GB platters, and the 500GB version with 2x250GB platters.

The 320GB Western Digital SE16 (caviar blue) also has a large single 320GB platter, which is a very fast smaller drive (I have 2 of them in RAID 0, really fast). I personally think these are a great deal for the money at $65 a piece.

Plus, the less platters = less noise and heat and power consumption, and shorter access times also! Therefore, the 640GB caviar black is the best choice for a larger hard drive at the moment, since it can be had for a great price (90ish bucks!) Plus, West. Digital has a good background in making reliable drives, and the black series HDD have 5 year warranty.

4x250GB platters for the 1TB Black and the Blue biggest drive is 750GB which is 3x250GB. Only difference in the Blue and Black series is the 32MB cache vs 16MB and 5yr vs 3yr warranty. Therefore they are a bit slower than the 640GB blacks with 320GB platters, with higher access times, take more power, and generate more heat, and are more noisy!

Actually, they might be using 3x333GB platters now... I'll look into it

Damn I got that caviar black! Anyway I still love it better than my 320 7200.10. Would it be a good Idea to get another 7200.10 and raid 'em?

I wonder how the seagate 7200.12 500Gb single platter fairs in Raid 0... perhaps in a future purchase... lol

Green, Black, Blue. All their 1TB drives have been using the 333GB platters for pretty close to a year now.

good raid cards are expensive. And they don't benefit RAID0 really (unless with SSD's).

That means that;

1. any cheap card will get good performance on raid 0

OR

2. no add-on card will get good performance on raid 0?
